Alexa earbuds and a new Echo: what to expect from Amazon's launch event

Amazon is gearing up for a huge launch on September 25, and rumors of new Echo devices are flying in the run up to the Seattle event. While Amazon hasn’t revealed what we can expect to see at the launch, we know from previous experience that these annual events tend to see in a host of new Amazon Echo hardware. Last year’s showcase saw upgraded Echo Dot and Echo Plus speakers, as well as far-out devices like the Echo Wall Clock and even an Alexa-powered microwave.Amazon&rsq
